I agree with Bobbi,
I had my thyroidectomy 4 months ago and I can honestly say that it has only been in the last few weeks that I've had glimmers of being normal, energetic, sleeping well, and living my life without actually (get ready for this) NOT thinking about my health. I felt much, much, much better right after the surgery as far as my hyper symptoms. Most of them were gone immediately, but a few lingered and still linger somewhat, but not nearly as bad as even 2 months ago. It's amazing how much time it really takes your body to adjust. I was fortunate in that my levels normalized after 1 Synthroid dose adjustment, but I didn't “feel” normal until about 2 months after that dose increase. Again, I still don't feel 100% pre- Graves me, but definitely closer than I was. I still get some tension headaches and feel a little off sometimes, but in general, even that is better than a month ago. Keep strong.
